T 0 all w ham it may concern:

Be it known that I, JEANTY Erorinniin'iann, a citizen of the Republic of France, and resident of Biarritz, Basses-Pyrenees, France, have invented certain new and useful Improvements in Receivers and Stenoh Traps for Sewers, of which the followmg 1s a specification.

My invention relates to a scentless sewer mouth which cannot be deranged or obstructed, and which may be joined to any street inclinations, owing to the fact that the parts constituting said sewer mouth,v1z, basin and cover, are mounted 111 a jointed way.

In the accompanying drawings, to which reference is being made Figure 1 is a front view with the rlght half in section, taken on line X-X of Figure 2.

Figure 2 is a side section on line Y- Y of Figure 1. D

Figure 3 is a plan view half 1n section on line ZZ of Figure 1.

Figures 4 and 5 are side views, the cover and basin being separated.

In taking reference to the drawmgs, this sewer mouth comprises two chief parts, the basin C, Figure 5, and the cover C, Figure 4:.

The basin is provided with a longitudinal partition a, the inferior edge of which is lower than the rim 6 of the basin. The faces 0, Figures 1 and 3, constitute parts of a straight circular cylinder s1de face, said cylinder having for axis the point 0.

Two ears 7 provided on these faces insure placing of the apparatus on the masonry.

The cover is also provided with a long1- tudinal partition d and the faces 0, Figure l, are cylindrical, their axis 0 mingling with the one of the basin when mounting takes place.

The basin C and cover C are united by juxtaposition of the partitions a and d by means of a bolt, the contact surfaces being lined with a plastic material for insuring tightness of the joint.

The whole is completed by a perforated plate 6.

The basin C lies flush, the edge C being united with the street curbstone, Figure 2. The upper part of the cover is made flush with the foot pavement and follows the inclination ,of same in swinging around the axis 0. Figure 1 shows in dotted lines. an

inclination given to the cover, the front face being on the same line as the rim. The perforated plate closes as a joint the sewer top on the pavement. The water coming from the street occupies in the basin the level of the rim 5. The lower edge of the partition a thereby becomes immersed. Said partition, owing to' its mounting, constitutes a whole with the partition 01. The whole a, d separates positively the sewer from the atmosphere of the street, thus rendering impossible any emanation to the exterior.

As this apparatus does not comprise any movable part and because it presents a great passage for the waters and residues of the street, it cannot get out of order, nor be obstructed.

The working of same is insured with respect to all inclinations of the cover with ability of varying same with respect to the basin level without altering the conditions of working.

It is to be noticed that this arrangement is provided in order to prevent rats from getting out of the sewer and into the street. To this end, the partition 0; which already constitutes an obstacle, is provided with sharp teeth at its lower edge. This arrangement prevents rats from reaching the street by swimming through the basin.

hat I claim is 1. In a sewer mouth, a basin, a longitudinal partition in said basin, ears on the outer face of said basin adapted to be engaged in the masonry. a cover, also provided with a partition, said partitions being secured together by means of a bolt, and a perforated plate covering the sewer top.

2. In a sewer mouth, a basin, a partition in said basin provided with teeth at its lower edge, a cover also provided with a partition, said partitions being secured together by means of a bolt, and a perforated plate covering the sewer top.

3. In a sewer mouth, a basin, a partition in said basin provided with teeth at its lower edge, a cover also provided with a partition,

means for securing these partitions together,

the walls of said basin and cover being of cylindrical shape so as to permit the cover of occupying any position with respect to the bottom of the basin, and a perforated plate covering the sewer top.

In testimony whereof I affix my signature.

JEANTY ETCHEBEHERE.
